How can the CN TOWER be more stable?
More stable than what? The CN Tower is based on a single, solid core. It is technically considered to be a structure rather than a building/skyscraper, because it’s not intended to support floors with office/residential space all the way up. Basically that means the CN Tower is thin enough so that everything can be supported by this core. Whereas with wider buildings (i.e. most office buildings) you usually have to have many vertical columns. Also the CN Tower is tapered at the top which makes it a more stable shape.
